South of Scotland was one of the eight electoral regions of the Scottish Parliament when it was created in 1999. The regional was replaced with South Scotland in 2011 following a review. Nine of the parliament's 73 first past the post constituencies were sub-divisions of the region and it elected seven of the 56 additional-member Members of the Scottish Parliament (MSPs). Thus it elected a total of 16 MSPs. The region had boundaries with the West of Scotland, Central Scotland and Lothians regions.
